[बूर्बुवः स्वरों जूं सः ह्रौं ॐ]- This is all known but what I have noticed is the importance of the first word त्र्यम्बकं trayambakam. *Traya=3, Ambakam=eye; meaning the one who is 3 dimensional, or 3 eyed one or 3 eyed reality or the one who sees 3 dimensionally or sees everything. *amba=mother; so traya/trya=3(brahma vishnu maheswara the hindu trinity), the mother of 3, that means it also represents the same message of gayathri mantra where it worships the one true god. *Here trya/traya can also represent 'THE THREE' or 'THE Trinity' that is vrahma(a), vishnu(u), maheshwara(m) meaning aum and the amba=mother. so traymabakam=brahma vishnu maheswara and the amba(mother) *if you consider here traya symbolizing the 3 eyed then amba the mother, so tryambakam may well mean shiva and amba or shiva and shakti or shashakti.
since stackexchange is becoming like reddit and wikipedia where unknown , behind the mask moderators run these sites like dictatorship, I have decided to add answers here. Chanting and reading are different. Vedic Chanting has two parts - Tone and Recitation (Patha). It further has four different tones - Udatta, Anudaatta, Svarita and Deergha Svarita. Pathas are the styles of hymnal recitation. So unless your are are well skilled in these and your pronouncination, enunciation is accurate, you are not supposed to chant. Chanting the same mantras in different way produces different effects, different vibrations. Many a times a slight difference in spacing, intonation, pronounciation, enunciation produces different meanings. So unless you are classically trained to chant these, one shall avoid it but can read them with sound without making a sound, silently. Ex: Many in north india swap va & ba. Ravindranath tagore becomes rabindranath tagore. Many in north india also swap ra & da
